As far as the question of making a living is concerned, sometimes fishing may cause an inbalance of marine life. However, for fisherman, they have no choice as they need to earn money by selling fishes. For hunters, they need to hunt for animals to survive but some of them may just hunt for their own excitement or sense of satisfaction. Some protesters strongly oppose hunting wild animals such as endangered animals. For example, they ban the use of fur, ivory, skin and feathers because they think that it is very cruel to kill the animals for unnecessary materials. In my view, it is best to save animals, so that they will not be endangered.
